-# Developing a codegen conversation
+
+
+
-## Usage
+# Substreams
-Using the local codegen for substreams init:
+Substreams is a powerful blockchain indexing technology, developed for The Graph Network.
-```bash
-SUBSTREAMS_CODEGEN_ENDPOINT=http://localhost:9000 substreams init
-```
+Substreams enables developers to write Rust modules, composing data streams alongside the community, and provides extremely high performance indexing by virtue of parallelization, in a streaming-first fashion.
-## Develop
+Substreams has all the benefits of StreamingFast Firehose, like low-cost caching and archiving of blockchain data, high throughput processing, and cursor-based reorgs handling.
-Install reflex `go install github.com/cespare/reflex@latest` and do
+## Documentation
-```bash
-reflex -c .reflex
-```
+Full documentation for installing, running and working with Substreams is available at: https://substreams.streamingfast.io.
-## Principles
+## Contributing
-You write a `Conversation` (or `Convo` for short) struct.
+**Please first refer to the general
+[StreamingFast contribution guide](https://github.com/streamingfast/streamingfast/blob/master/CONTRIBUTING.md)**,
+if you wish to contribute to this code base.
-- This function embed or has a `State` variable with the state you want to build.
- - This _State_ is what gets serialized to JSON and sent to the client. It must be a usable interface, so pick your names wisely.
- - Anything that is exported will be shared with the client, and come back during hydration (if a connection gets interrupted, or the user kept their `generator.json` state, and wants to simply rebuild).
-- It has an `Update()` method that is registered into the `loop.EventLoop` by the `codegen` framework.
- - This function can mutate state, and it is the only method who can mutate state.
- - This function follows the ELM paradigm, and must never do long-running operations, only quick routing.
- - A `NextStep()` function will choose where to go based on the current state, and continue the conversation to make sure it is valid and completely filled in.
- - Any long running work is done in a `loop.Cmd` (that runs async), and that Cmd returns a message for error handling or continuation.
- - Any loops are done by sending a `loop.Cmd` that does an iteration, and returns a message to continue the loop. The ending condition is merely the rescheduling of that same Cmd (or not, to end the loop).
-The code generation:
+## License
-- Any `gotmpl` files will go through templating, and be passed the _State_ struct as a single parameter.
-- The _State_ struct should have helper methods to allow getting data from the state
